4x4 Posi Lok - parts Kit - Photo 02

The Posi-Lok kit is not complicated. A pull-cable actuator comes with brackets to place it on the front differential. The cable pushes a pin that presses on a shift fork to engage a collar over the outer passenger axleshaft and the intermediate shaft. This goes for the Jeeps, the Dodges, and the Chevys. Our particular kit was to fix a '94 K-Series fullsize Blazer.
